The Varia is a wonderful and, I believe, necessary addition toward safer riding. Not only are you able to have several option for the rear light, but you get a very clear image on your GPS computer of the traffic mounting behind you.
Before the Varia, I was always guessing and mostly trying to listen to what traffic was approaching. Now I have such a better sense of what my environment is like in a split second on the bike. It allows me an initial snapshot and really eases my concerns especially on single lane roads, turn left endeavors and overall solo riding. I especially love it on group rides. I now have a better idea of what is behind me while passing others and when to hug the road. Equally, no more last second "car backs" but rather a much better heads up warning.
Wish I had purchased this earlier.
I didn't think I wanted or needed this, but my friend convinced me to try it. It's a game changer. The unit picks up cars well before I hear them especially on descents when wind noise blocks car sound. The display is excellent telling me the number of cars approaching and their closing speed. I love that closing speed information as I will move over as far as I can and as quickly as I can if I know a car is going really fast. A truly fantastic product.
For the past few years, I had considered purchasing the Garmin Varia' RTL515, but each time decided against it. My rationale was that I currently cycled with lights (day/night), and that the radar light combo on the Varia' RTL515 would simply be overkill. I was wrong. The first thing I noticed was that cars appeared to give me a wider birth when passing on open roads. At first, I thought it might be the placebo effect of my new tech purchase, but after several weeks of continued safe passes, I wonder if it might be something else -- the flashing pattern of the light, the possibility that driver's see the Varia' and assume it's a camera, etc? For the type of cycling that I do, the Varia' RTL515 is the ideal tool to help me keep safe. 75% of my riding is on open roads, many of which are rural. I cannot think of the time when the radar didn't detect a vehicle before I heard the vehicle. The Varia' RTL515 It tells me what's behind (displayed on my Edge 840) and adds the provided safety of a rear light. I highly recommend.
I had always seen these on other bikes and never really understood how one could justify buying such an expensive "light". After just a few rides I won't ride without this. The peace of mind I have now knowing what is coming up behind me absolutely makes this little gadget worth the price. The ability to turn the light on/off from your head unit is also an understated feature but a nice thing to have to preserve battery when you're not riding on a road.
I ride a lot of great backroads in forested countryside. At 18-20 mph It's hard to hear or see cars coming from behind so it's hard for them see me too. Rtl515 bright light and early warning radar let me be seen and ride to the side with plenty of time. Still always check over my shoulder but this added check gives me more Confidence that I don't miss anything. Great to only charge 1 instead of 2 accessories also and takes way less space than sprig and radar I used to use. . I get about 4-5 hours on a charge. Just enough for most rides.
Have been using an RTL510 for 6-8 months, now won't ride without it. Useful in ways I hadn't imagined: (a) on fast descents when it's too dangerous to look back, it tells you if traffic is coming up behind you, (b) tells you if it's safe to move left to avoid bad pavement, (c) if you need to turn left, it helps you tell if a clot of traffic is approaching from behind, (d) while it doesn't display the lateral position of a vehicle passing you, you should expect a close pass if it shows that a pass is happening close to a blind corner or crest, or oncoming traffic. Also, I was unaware that its flash rate increases when traffic is approaching from behind until one day in my car I came up behind a RTL-equipped cyclist - quite a light show!
Limitations: (a) in high-traffic areas it will alert continuously (I avoid areas like that anyway), (b) if you are cycling along a secondary road paralleling an expressway, it may pick up traffic on the highway, (c) on curvy or rolling roads, terrain may block the radar beam long enough for a contact to be temporarily lost, reappearing as it gets closer. You should double-check with a head turn when it's important, because the RTL gives a low rate of false positives (not critical) and a lower rate of false negatives (critical!) in certain specific situations. The false positives seem to be triggered by motion-detecting lights or cameras (I routinely get false alerts when passing certain facilities). Occasionally it may temporarily show multiple dots when there is only a single vehicle, or "miss" a vehicle following closely behind another. False negatives happen when an upcoming vehicle slows to wait for a safe opportunity to pass me, so that it is going at my speed, no longer approaching me. If that situation persists long enough, that vehicle may vanish from my screen, making an abrupt left turn risky. Have gotten these false negs a number of times.
All in all, the RTL is a huge plus, greatly reducing the amount of shoulder-checking I have to do, so I wobble less and scan the road ahead more closely.
Purchased for a planned cross country trip. I am hearing impaired and I wanted something that would help identified vehicles approaching from the rear on open roads with no shoulders in windy or noisy environments. I now have ~ 1000 miles of use on it riding solo and in a group over the past month. Works great and does exactly what I had hoped. It gives you ~ 5-7 seconds of notification when vehicles are approaching @ 50-60 mph. This is more than enough time to make any necessary adjustments to your riding. My only gripe is the Garmin Edge 1030 audible alarm isn't loud enough for me to hear (common complaint). However, using the Varia App I am able to hear the phone audio alarm (volume controllable) and feel it vibrate in my Jersey pocket. I would recommend this product for anyone who wants to be aware of vehicles approaching from behind. On a side note. It would be kind of cool if the App or your control unit kept track of the total number of vehicles that passed you. Seems like it would be easy to write the code for an easy software upgrade.
I have been using the earlier version of Varia Radar 2 for a bit over two years. I have been told by drivers, among them two FedEX drivers, that it is the most effective tail light they have ever seen. It was visible at a distance of more than a mile. It begins flashing as soon as a car comes within the radar range. I ride just about every day and I have never been surprised by a vehicle coming up behind me. My computer beeps and the display of the vehicle or vehicles approaching shows along the right side of my Edge 1030. I can judge the speed and distance of the approaching vehicle from the display. It really is a remarkable piece of equipment, and it sounds like they have made it even better. My unit will start giving me a low battery warning after about 4 hours on a ride. I have never run out of battery, but my rides don't usually last longer than 4 hours. The longer life battery is certainly not a waste. To give some idea of the sensitivity of the radar, I was once standing by the side of the road taking a break when a runner I had passed earlier approached. The computer beeped, and the display showed the runner approaching. That is pretty amazing. Yet, at the same time, when I have ridden with another rider, his presence is not noticed by the radar, only cars approaching us. The stimulus for the radar is something approaching, not something keeping pace with you. Recharge time is about an hour or less. It is, in my opinion, a necessity if you ride on the road. It will pair with most Edge computers and, also, with Wahoo computers.
My PDW asteroid taillight finally gave up the ghost so I decided to upgrade to the Garmin radar & taillight and I couldn't be happier.
Love the integration with my wahoo bolt roam, super easy to set up, has a great range for detecting cars, and the lights are bright and visible day or night.
As I'm sure others have noted, it only detects traffic closing with a speed differential so if a car is matching your speed, it can disappear from the display. This isn't really a problem, as you shouldn't be relying solely on the radar to tell you what's around.
Where it really shines is on solo rides on backroads where it will detect a car coming well before you'd be able to hear it.
Overall it's well worth the money and I wish I had picked one up sooner.
Ok......been using this product for quite some time so I feel my review is accurate. The visibility of the light itself is awesome and cagers should easily see you. The light patterns you are sure to find one that suits your need. The ability to sync to your Garmin or even other cycling computer and control is a plus. Battery life depending on light mode is good. If you are doing a several hour ride just make sure you select longest light mode and have light freshly charged. The radar works great in my findings and on long unobstructed straights you get several hundred feet of advanced warning. You can also get the widget for,your Garmin computer to allow you to see the total vehicle count that passes you and the distance back as they close in on you. The sturdiness of the product and water resistance is very good. As my title states......an invaluable piece of cycling hardware!
Occasional software issue--1/10 rides-- where audible car alert will not work on iphone 11 used as a control device through the Garmin app. The visual alert has never filed to work. This seems to happen once charge on the radar is at 40% or less. Annoying, and Garmin tech support is not particularly responsive, nor do they follow up.
That said, it's an amazing device, which detects cars flawlessly and I can't imagine road riding without anymore.
Light is compatible with my edge and alerts one of vehicles. The light is bright and has several options. Charging the unit is simple.
Two things, an easy way to be made aware of cars approaching behind you and a really bright tail light to help you be seen by those cars. I will not ride without this, best accessory I've ever purchased
I have had the Varia for a couple of years. The light works fine and the radar works great with my Garmin 1030. The best/safest solution is to use the Varia with a bike mirror: one warns you to watch and by watching you can take evasive action if needed. If I were just starting out riding on the roads I would pair the Varia RTL515 to my phone and use a mirror while riding.
My son says this is all rationalization for buying the Varia RTL515 because riding on the road is crazy and to think my 73 yr old "catlike" reflexes will save me from being hit is a fantasy. But hey, I am a believer.
I've always used a rear view mirror attached to my glasses and thought there was no need for a Varia Radar sensor. Boy was I wrong'! Immediately on my first ride with it I was amazed as to how terrific it was. Now I rely on it every time I ride. Especially if I ride solo.
I've been riding for over 15 years on the same, primarily rural roads and know the traffic. However, in the last year, I added a mirror, which is suitable for looking behind but wasn't convenient. I purchased the Garmin Varia RTL51 5 Rear Radar on sale, and using it in conjunction with the mirror has brought back a comfort level to riding on the roads again. The Varia alerts me to an approaching vehicle (or vehicles), which I can check in the mirror, and then alerts me when traffic has cleared - good for multiple vehicles, especially trucks with trailers. I find the combination of radar and mirror immensely helpful and reassuring in providing another layer of safety on the road.
I'd been leery of the price yet consistently blown away by the positive comments on the Varia and finally ordered it a few months back. The positivity is 100% warranted. I've used it in the dark, in the day and during large group rides and have found all the modes pretty fantastic. It may be a placebo effect but I feel like cars give me a wider berth since I've been using it, too. The best part is that you can relax and enjoy the quiet roads even more, knowing you're free and clear. About the same time you can hear tires behind you, the Varia detects the car coming and you can move over.
I bought one early on and have been using it continuously until just recently after surviving multiple drops from my recumbent bike bag while cruising over bumps at 20+ mph, I dropped in onto my concrete garage floor and it became unreliable. I nursed it until my new one arrived, and ordered a backup just in case. BTW, I got one for my wife's recumbent Catrike too. The Garmin picks up cars just after I can see them in my mirror. So, if I have not seen by the time it beeps, it's time to react to the car. It keeps me warned on expressways and multilane residential streets of high speed vehicles.
After initially scoffing at the idea of the Varia radar as being yet another piece of electronics for the bike I finally grew tired of cars sneaking up on me and with a 25% discount from WesterBikeWorks finally pulled the trigger. I was an idiot for not buying it sooner. That's no joke. It's great getting alerted to approaching cars particularly on windy days where I can't readily hear them. I have the single radar paired to both my Garmin as well as my wife's so when we ride together we can both take advantage of it. The light is bright and very difficult to miss (and blinding on group rides when people don't set it to a lower intensity). The only negatives I've found is the included universal mount is so-so on my round seat post and will be replaced by the Garmin clasp type mount in the future. The other negative is you can't use it while charging, meaning on a long ride you need to be conscious of which light mode you're using so you don't run out of battery.
Always thought my hearing was good enough to hear traffic coming up from behind me. It took only one ride with the Varia to appreciate the benefit of having radar. Let's me know traffic is approaching before it can be heard. Also shows when multiple vehicles are approaching. It easily paired with my Garmin 530. Had my wife drive up behind me while I was riding and she noted the high visibility of the light. Definitely an essential part of my riding gear to be used on every ride.
